Typical Applications
BTS52001ENAXUMA1 is suitable for 6 applications: 12V Automotive R10W Lamp Driver, LED Tail-Lamp and Ambient Lighting Driver, Body Control Module (BCM) Load Outputs, Resistive Load Switching in Junction Boxes, Industrial 24V PLC Discrete Output, Replacement of Electromechanical Automotive Relays.
12V Automotive R10W Lamp Driver
The BTS52001ENAXUMA1 is specifically designed by Infineon to drive 1× R10W 12V incandescent lamps in automotive body electronics. Its 200 mΩ RDS(on) keeps conduction losses low (P = I²R ≈ 0.45 W at 1.5 A), while the integrated charge pump and N-channel MOSFET ensure true high-side switching without external bootstrap. Compared to a discrete MOSFET + relay solution, the integrated current limit protects against the cold-filament inrush (typically 8× nominal current at turn-on), and the thermal shutdown with auto-restart handles prolonged short-circuit events - critical for turn-indicator and rear-lamp reliability targets.
Recommended
LED Tail-Lamp and Ambient Lighting Driver
For automotive LED tail-lamp modules and interior ambient lighting, the BTS52001ENAXUMA1 provides clean PWM-dimmable high-side switching with diagnostic feedback. Its 4.5-28 V operating range covers cranking and load-dump transients on the 12V bus, and the open-load detection in OFF state catches failed-LED conditions for ASIL-relevant safety reporting. The exposed-pad PG-TDSO-8-31 package dissipates the I²R loss efficiently across a 1 cm² copper pour, enabling compact lamp-module PCB designs without an external heatsink.
Recommended
Body Control Module (BCM) Load Outputs
In a body control module, the BTS52001ENAXUMA1 replaces legacy electromechanical relays with a solid-state high-side switch for loads such as door-lock motors, mirror heaters, and seat adjusters up to 1.5 A. The logic-level active-high input is directly compatible with 3.3 V or 5 V microcontrollers, eliminating the need for a gate-driver stage. The integrated diagnostic pin feeds back to the BCM MCU for fault management, and the AEC-Q100 qualification satisfies OEM automotive quality requirements for underhood and cabin-mounted ECUs.
Recommended
Resistive Load Switching in Junction Boxes
Automotive junction boxes use the BTS52001ENAXUMA1 for centralized switching of resistive loads such as heated mirrors, seat heaters, and small PTC auxiliary heaters. The 200 mΩ RDS(on) keeps self-heating manageable inside the sealed junction-box enclosure, while the load-dump robustness protects the device during alternator-battery disconnect events. Multiple BTS52001ENAXUMA1 channels can be paralleled with separate diagnostic lines, though Infineon typically recommends the BTS5210GXUMA1 dual-channel part for higher-density junction-box designs.
Recommended
Industrial 24V PLC Discrete Output
Beyond automotive, the BTS52001ENAXUMA1 can drive 24V industrial loads up to 1.5 A in PLC discrete-output modules, offering logic-level control, over-current protection, and fault feedback in a single SO-8 equivalent package. The 4.5-28 V operating range covers nominal 24 V industrial rails with adequate transient margin. Although not AEC-Q100 mandated in industrial settings, the part's automotive-grade robustness provides superior reliability for factory-automation discrete I/O.
Recommended
Replacement of Electromechanical Automotive Relays
The BTS52001ENAXUMA1 is an ideal drop-in solid-state replacement for 12 V automotive relays in applications where silent operation, longer lifetime, and diagnostic feedback are required. It eliminates relay-coil current draw, contact bounce, and mechanical wear while adding open-load and short-circuit protection. The PG-TDSO-8-31 footprint allows PCB-direct substitution in many relay-driver PCB layouts, particularly in next-generation BCM designs targeting ISO 26262 functional safety compliance through electronic rather than electromechanical switching.

Key Differentiators

- Integrated diagnostic feedback for functional-safety compliance (vs BTS52001EJAXUMA1)
Design Notes
Estimated: at 1.5A continuous load and 200mΩ RDS(on), the steady-state conduction loss is approximately P = I²R = 1.5² × 0.2 = 0.45W. With the PG-TDSO-8-31 package mounted on a 1 cm² copper pour (theta_JA ≈ 50 K/W per datasheet), the junction temperature rise is roughly 22.5 K above ambient - well within the 150 °C junction limit. For sustained operation near 1.5A, increase the copper area to at least 2 cm² to maintain margin.
Solder the exposed thermal pad of the PG-TDSO-8-31 package to a continuous copper plane on the top layer with multiple thermal vias to the inner/ground plane. Place the input decoupling capacitor (typically 100nF) within 5mm of the IN pin, and the VBB bulk capacitor (typically 10-47µF) within 10mm of the VBB pin. Route the high-current OUT trace with at least 1mm width per ampere to avoid copper-heating side effects.
Do not leave the diagnostic (IS) pin floating when unused - connect it to GND through a pull-down resistor or to the MCU ADC input. A floating IS pin can pick up noise and falsely trigger fault diagnostics. Also note that the BTS52001ENAXUMA1 does NOT include reverse-battery protection on VBB; for reverse-polarity protection add an external P-MOSFET or Schottky diode in series with VBB per Infineon application note AN-100.
